Communication method utilizing fingerprint information authentication

Abstract

A communication method utilizing fingerprint information authentication comprises the following steps: (a) extracting fingerprint information of first, and sending a request instruction to second user via the fingerprint information by a first user on an information exchange platform, and extracting fingerprint information of second user after receiving the request by the second user, and storing the fingerprint information in the information exchange platform and exchanging it with first user by the second user to confirm their identity; (b) inputting a message to be sent in an encrypting unit to obtain encrypted message by the first user after passing authentication, and transmitting the encrypted message to a communication application unit and sending it to second user, and receiving the encrypted message via the communication application unit by the second user; (c) decrypting the encrypted message by means of the decrypting unit by the second user after passing authentication.

What is claimed is:  
     
         1 . A communication method utilizing fingerprint information authentication, comprising the steps of:
 (a) extracting fingerprint information of a first user by means of a collection and recognition device of a fingerprint sensor and transmitting the fingerprint information to a information exchange platform, sending a request instruction to a second user through the fingerprint information on the information exchange platform by the first user, and confirming the request after receiving the request instruction by the second user and extracting fingerprint information of the second user by means of the collection and recognition device of the fingerprint sensor, and storing the fingerprint information of the second user in the information exchange platform and exchanging the fingerprint information of the second user with the first user to verify their identity;   (b) extracting fingerprint information of the first user and authenticating the identity of the first user by the collection and recognition device of the fingerprint sensor, inputting a message to be sent in an encrypting unit by the first user after passing the authentication, to obtain an encrypted message, and then transmitting the encrypted message to a communication application unit and sending it to the second user, and receiving the encrypted message via the communication application unit by the second user;   (c) extracting fingerprint information of the second user and authenticating the identity of the second user by the collection and recognition device of the fingerprint sensor, and decrypting the encrypted message by means of a decrypting unit and reading the decrypted message by the second user after passing the authentication.   
     
     
         2 . The communication method utilizing fingerprint information authentication as claimed in  claim 1 , wherein
 in step (a), extracting fingerprint information of the first user by means of the collection and recognition device of the fingerprint sensor and generating a first public key and a first private key corresponding to each other, storing the first private key in a memory of the fingerprint sensor and storing the first public key in the information exchange platform, and sending a request instruction to the second user via the first public key by the first user, and confirming the request after receiving the request instruction by the second user and extracting fingerprint information of the second user by means of the collection and recognition device of the fingerprint sensor and generating a second public key and a second private key, storing the second private key in the memory of the fingerprint sensor, storing the second public key in the information exchange platform and exchanging the second public key with the first public key of the first user;   in step (b), extracting fingerprint information of the first user by means of the collection and recognition device of the fingerprint sensor, and comparing the fingerprint information to the first private key stored in the memory of the fingerprint sensor in step (a), and if consistent, the first user passing the authentication;   in step (c), extracting fingerprint information of the second user by means of the collection and recognition device of the fingerprint sensor, and comparing the fingerprint information to the second private key stored in the memory of the fingerprint sensor in step (a), and if consistent, the second user passing the authentication.   
     
     
         3 . The communication method utilizing fingerprint information authentication as claimed in  claim 1 , wherein the information exchange platform is a host computer or server. 
     
     
         4 . The communication method utilizing fingerprint information authentication as claimed in  claim 1 , wherein the communication application unit is selected from the group of micro blog, QQ, MSN, SKYPE or any combination thereof. 
     
     
         5 . The communication method utilizing fingerprint information authentication as claimed in  claim 1 , wherein information transmission between the first user and the second user via the communication application unit can be achieved by any one of network, infrared, Bluetooth or any combination thereof.
